Problem with Embedded Files/Collections

I have written a Pdf file (fragments below) to act a container to other pdf's. Initialy it all looks good, however when I click on the embedded file inside Acrobat Reader instead of displaying the contents I get a thumbnail of the acrobat logo with the Open and Save options underneath. If I click open it opens a new Reader window with the container file displayed again, not the embedded file. However if I click save it saves the embedded file down to disk correctly.

How can I make it so that when the file is clicked in the attachments window it opens directly into the main reader window?
